Phys.org / Ancient turtle hunting could inform modern conservation throughout southern Caribbean
Despite the promise of rebounding green sea turtle numbers, many sea turtle populations continue to flounder under the pressures of changing climates, overfishing and urbanization.
Tech Xplore / Massive quantities of undeclared uranium are exported from the DRC, study reveals
University of Wisconsin–Madison and Princeton University nuclear engineers have identified a major blind spot in nuclear accounting with global nuclear security implications.
Phys.org / Scientists discover 210-million-year-old dinosaur in Zimbabwe
A newly discovered dinosaur from Zimbabwe is offering fresh clues to how the animals diversified, suggesting they spread across distinct ecosystems in southern Africa, scientists said Wednesday.
Phys.org / Gobi fossil reveals 6-inch 'Cretaceous rabbit' belonged to a different mammal branch
A remarkably preserved fossil from Mongolia's Gobi Desert is reshaping scientists' understanding of mammal evolution during the age of dinosaurs.
Phys.org / Most complete skeleton of 30 million-year-old dog discovered
For decades, a 30 million-year-old fossil sat entombed in rock in an Oregon museum collection. When it was first found, paleontologists thought it might be an early relative of sheep, camels and pigs, whose fossilized skeletons ...
Phys.org / Tiny fossils crack a Cretaceous cold case: Ocean acidification triggered one of the ocean's most severe extinctions
A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest ...
Phys.org / Likelihood of wildfires in Southern Europe has doubled since the 80s, study shows
Summer days featuring conditions that promote wildfire ignition, intensity and spread have more than doubled across large parts of the Iberian Peninsula, France, Italy and Greece since 1981, according to a study in Scientific ...
Medical Xpress / Simple triage protocol cuts ER wait times without adding beds or staff, new study finds
Emergency departments across the country face a common challenge: how to reduce long wait times without adding more beds, hiring more staff or expanding facilities. New research suggests one answer may be hiding in plain ...
Medical Xpress / Overlooked plant proteins may boost gut health
Plant-based diets are good for you. They promote gut, immune, metabolic and cardiovascular health, in part by cultivating a diverse community of intestinal bacteria. These benefits have long been known to stem partly from ...
Phys.org / Hubble shows star formation in Andromeda galaxy is winding down
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
Phys.org / In biology of cells, octopus has another trick up its sleeve
The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core ...
Tech Xplore / Vacuum attachment designed to improve nuclear fallout collection
In a nondescript Idaho Falls warehouse, a nuclear nonproliferation researcher at Idaho National Laboratory (INL) picks up a small plastic bottle and pours tiny bits of rounded black glass across a worktable.
